Sipai,
I didn't get your attatchment, so let me try some guesses:
To get a column from a matrix in list form:
IN>
matrix = {{1, 2}, {1, 2}, {1, 2}}
column = Column[matrix, 1]
OUT>
{{1, 2}, {1, 2}, {1, 2}}
{1, 1, 1}
To create a list from nested lists, use Flatten[]:
IN>
columnVec = {{1}, {2}, {3}}
list = Flatten[columnVec ]
Out[268]={{1}, {2}, {3}}
Out[269]={1, 2, 3}
To create a list of x,y pairs (eg. for ListPlot[]) from separate x & y
lists, I use the following:
IN>
x = {1, 2, 3};
y = {4, 8, 12};
pairs = Transpose[{x, y} ]
OUT>
{{1, 4}, {2, 8}, {3, 12}}
-mark harder
